Title: An adapter
IPC: H04L29/08
Filed: 1970-03-17
Abstract: 1,255,432. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORP. 17 March, 1970 [2 April, 1969], No. 12649/70. Heading H4P. A telegraph receiver which can receive startstop-signals at various bit-rates tests for the presence of the stop bit in a received character at the time expected according to the bit-rate at which the receiver is set and if absent the receiver is reset to either an alternative bit-rate or in another arrangement to one of a number of bit-rates which the receiver successively tries. The receiver is under the control of a processor which initially puts the receiver into a receive state. The next received character start bit, identified by a mark/space transition, set to a count of 5 a 3-stage binary counter driven by clock pulses. Upon the count of 7, and subsequent counts of 7, the state of the received signal is sampled and signalled to the processor. After receiving the number of samples equal to the character bit-length corresponding to the character speed to which the receiver is set the processor instructs the receiver to sample what should then be a stop, indicated by a mark. Failure to detect a mark causes the receiver to be reset for the next character with the counter driven at a different clock rate corresponding to a slower bit rate. In one arrangement only two clock frequencies are available but in another arrangement a shift register is clocked on one stage to gate one of several frequencies to the counter. In a further arrangement a counter acting through a decoder selects the frequencies as the same character is successively tested for its stop at different possible stop times. In all arrangements a condition of the character coding is that no character may not have a bit at the mark level when it is time for the stop bit (mark) of a higher rate character.

Title: Improvements relating to automatic and semi-automatic telephone systems
IPC: H04Q3/42
Filed: 1925-02-19
Abstract: 253,851. Siemens Bros. & Co., Ltd., and Humphries, H. E. Feb. 19, 1925. Automatic exchange systems.-First code selectors are provided with two sets of wipers, the set to be used being determined by the setting of the office register before the register controller sends the first code digit. The invention is described with reference to a system of the kind described in Specification 252,244, in which the control of the selectors by the register controller involves both forward and reverting impulses. The first code selector, Fig. 2, is, apart from the wiper changing relay MC, identical with that shown in Fig. 6 of that Specification. The register-controller, Fig. 3, is the same as that shown in Fig. 7 of that Specification, except that it is not provided with means for giving release control to an operator and the relay B is connected to the wire a over a contact a6 instead of direct. The Strowger office-register CS has a bank 24 in which the terminals representing offices reached over wipers A1, B1, C1 of the first code selector are jumpered to the wire W, the remaining terminals being left unconnected. Consequently, when such a code is received, the relapse of the dialling relay DX completes a circuit 24, W, dx4, ocf, u6, cfa, tf2, vm, aa3, MC(1). Wiper changing relay MC locks up over its winding 2, its first winding being disconnected when the selector moves, at vm and then at l5. The transmission of the first digit does not begin until, as described in Specification 252,244, relays B, U, fall back. The wire W is then disconnected from the wire a at u6, and subsequently. when the sequence switch OC moves on for the second digit by the extra wiper ocf. Specification 200,928 is referred to.

Abstract: 717,982. Scoop arm machines. EIMCO CORPORATION. May 21, 1952 [June 7, 1951], No. 12841/52. Class 68(1) [Also in Group XXX] A swinging sector shovel of the kind in which the winch drums which effect rocking movement of the shovel supporting sectors are driven from a power take off shaft on the tractor through a clutch mechanism having a driven element which can be braked, and a control lever which, selectively, engages the clutch elements and disengages the brake, and disengages the clutch elements and applies the brake is characterized in that an addition control member disengages the clutch elements when actuated by the shovel in its elevated dumping position. The control lever 200 is secured to a spindle 202 which carries a pair of clevis members 218, 220 operatively connected through linkages with the brake band 166 and clutch operating levers 226 respectively; the arrangement being such that when the band 166 is tightened the levers 226 are moved to a position where they disengage the clutch (not shown) and vice versa. The linkage connecting clevis 220 with levers 226 comprises a bell crank 224 pivoted at 542 to a link 238 in turn connected to a lever 236 which operates a rock shaft 228 keyed to levers 226. The bell crank 224 is also pivoted at 543 to a rod 256 which is normally stationary and so does not affect the operation of the clutch through lever 200, but which is adapted to break the toggle connection between the bell crank and link 238 at 542 and so disengage the clutch, when it is moved linearly by a linkage connected with a movable abutment bar (not shown) which engages the bucket at the end of its lifting movement. This linkage (not shown) which is connected to the rod 256 through a bell crank 262 and rod 266, has a spring which tends to maintain the abutment bar and rod 256 in unoperated positions and so causes the bucket to oscillate when in its raised position with the lever 200 in its clutch engaged position, so discharging material adhering to the bucket. A switch 294 co-operating with a member 296 on the upper lever 226, and in circuit with the tractor starter motor ignition system, prevents this motor from starting if the clutch is engaged. A toothed sector 206 co-operates with a pawl 212 to retain lever 200 in its brake operated position. The complete shovel mechanism is made as a unit which is quickly detachable from the tractor.
